pounds

Explanation:

Step1: Find the rate of trash pickup

The rate is pounds of trash per hour. Last month, they picked up 8 pounds in 4 hours, so the rate $r = \frac{8}{4}$ pounds per hour.
$\frac{8}{4}=2$ pounds per hour.

Step2: Calculate this month's trash pickup

This month they work 3 hours at the same rate. So the amount of trash $T = r\times t$, where $t = 3$ hours and $r = 2$ pounds per hour.
$T=2\times3 = 6$ pounds.
